Abstract

An abrasive article including a bonded abrasive body coupled to a core, the core includes a composite material including an organic material and a metallic material, and the composite material includes at least a first filler that can include nitrides, carbides, borides, oxides, silicates, or a combination thereof.

Claims

1. An abrasive article comprising:

a bonded abrasive body coupled to a core, wherein the core comprises a composite material including an organic material and a metallic material, and wherein composite material includes at least a first filler selected from the group consisting of nitrides, carbides, borides, oxides, silicates, or a combination thereof.

2. The abrasive article of claim 1, wherein the first filler includes a polycrystalline material.

3. The abrasive article of claim 1, wherein the first filler consists essentially of a polycrystalline material.

4. The abrasive article of claim 1, wherein the first filler comprises a material selected from the group consisting of a silicate, a carbide, or a combination thereof.

5. The abrasive article of claim 1, wherein the first filler comprises wollastonite.

6. The abrasive article of claim 1, wherein the first filler consists essentially of wollastonite.

7. The abrasive article of claim 1, wherein the first filler comprises silicon carbide.

8. The abrasive article of claim 1, wherein the first filler is present in a first content (Cff), and the core comprises a minority content of the first content for a total weight of the core.

9. The abrasive article of claim 1, wherein the core comprises a first content within a range of at least 1 wt % and not greater than 30 wt %.

10. The abrasive article of claim 1, wherein the organic material comprises a polymer.

11. The abrasive article of claim 1, wherein the organic material comprises phenolic resin.

12. The abrasive article of claim 1, wherein the core includes at least 60 wt % of the composite material for a total weight of the core.

13. The abrasive article of claim 1, wherein the abrasive body comprises a dampening factor of at least 0.007.

14. An abrasive article comprising:

a bonded abrasive body coupled to a core, wherein the core comprises a composite material including an organic material and a metallic material, and wherein the core comprises a flexural strength of at least 60 MPa and a dampening factor of at least 0.007.

15. The abrasive article of claim 14, wherein the composite material includes a first filler.

16. The abrasive article of claim 15, wherein the first filler includes a polycrystalline material.

17. The abrasive article of claim 15, wherein the first filler consists essentially of a polycrystalline material.

18. The abrasive article of claim 15, wherein the first filler comprises a material selected from the group consisting of a silicate, a carbide, or a combination thereof.

19. The abrasive article of claim 15, wherein the first filler comprises wollastonite.

20. The abrasive article of claim 15, wherein the first filler consists essentially of wollastonite.
